Drew Barrymore has hit back at trolls who left her feeling ''hurt'' by posting ''cruel'' messages on her Instagram.

The 42-year-old actress was left feeling down about herself after a flurry of nasty comments were left on a selfie she posted, in which she is sat on a boat wearing a pair of orange sunglasses.

The '50 First Dates' star had her confidence knocked by the mean words and decided to go to the beauty parlour to get a new hairdo to lift her spirits, however, she also reminded her 7.8 million followers that ''a little love on the outside never hurts''.

Sharing a picture of herself getting her hair done, she captioned the post: ''Haters gonna hate. Yesterday I saw comments on my Instagram feed about my post that were mean, cruel, and ugly. It hurt me. And you know what women do when they get hurt???? They pick themselves up! Go get a haircut. Put on some lipstick and chant ''if you don't have something nice to say... don't say anything at all'' thank you @markishkreli @yumi_mori for picking a girl up and dusting her off. And more than anything, helping me feel pretty. Pretty is on the inside. But a little love on the outside never hurts. #thisfeedisforlovers (sic)''

The 'Never Been Kissed' star is all about being a ''positive inspiration'' to fellow females, and recently launched a new lifestyle brand named Dear Drew.

Drew's first clothing line includes a range of garments as well as jewellery pieces and additional accessories that retail from $28 to almost $300 on Amazon Fashion.

The blonde beauty's latest venture was designed to ''provide positive inspiration'' to ''all women''.

Speaking about the range, Amazon Fashion Director, Kate Dimmock, said: ''The brand's mission is to provide positive inspiration and a grounding voice to all women.''
